It isn't about personalities or apathy, that's the politicians' mantra not the reality. It's about being sick to death of having the choice of two parties that control every aspect of our lives, that play the divide and rule card with immigration and class, that use education as a vote winning tool rather than using education as a tool to educate, that long since gave up representing us as a population as they seek to gain election on policies that the right wing media support etc, etc, etc.
Anyone with a brain soon learns that they can't change anything, the political debate is so controlled and so small that change is impossible. The first past the post electoral system means that we're forever stuck in between a gnat's hair of Labour and Conservative. We are where we are and we'll go where we go regardless of what you or I vote for. We're an irrelevance, all that matters is that big business is catered for. This would be great if the money filtered down as Thatcher believed it would but as it doesn't...
Keep voting though if it makes you feel superior and like you're making the slightest jot of difference. If you're in favour of maintaining what we have regardless of the colour of party in power then your vote won't be a wasted one.
